Definitions

  • the present invention relates generally to the field of endoprosthetic devices and more particularly to improved femoral inserts for total hip replacement.
  • the replacement comprises a cup member secured to the pelvis, by either a cement such as methyl methacrylate or by bone growth, a ball and a stem member secured within the intermedullary cavity of the femur, also either by a cement or bone growth.
  • the ball is secured to the stem member and rotatably received by the cup member.
  • stem structure must be adapted for insertion within the femur, while preferably displacing only a minimal amount of biological material. Otherwise the femur is weakened to the point where fracture becomes a significant danger.
  • FIG. 1 is a lateral cross-sectional view of a femoral insert embodying various of the features of the present invention, secured in a femur.
  • FIG. 2 is an elevational view of a femoral insert embodying various of the features of the present invention.
  • FIG. 3 is a cross-sectional view of the femoral insert of FIG. 2, taken along line 3--3.
  • FIG. 4 is a cross-sectional view of the femoral insert of FIG. 2 taken along line 4--4.
  • FIG. 5 is a cross-sectional view of the femoral insert of FIG. 2, taken along line 5--5.
  • FIG. 6 is a partial elevational view of the femoral insert of FIG. 2, taken along line 6--6.
  • FIG. 7 is an elevational view of a femoral insert stem embodying various of the features of the present invention, resting medially upon a planar surface.
  • the stem derives support from all of the adjacent media, but most important is the stem support in the proximal medial region of the calcar and the support on the lateral surface of the stem.
  • the stem must be supported by stiff media in the region of the calcar. Because the cements used, i.e. primarily methyl methacrylate, are generally less stiff than cortical bone, this means that the stem should rest directly upon cortical bone or on a thin layer of cement between the stem and cortex in this region.
  • proximal lateral support of the stem moves the resultant constraint force more proximally, thus distributing bending stresses in the proximal portion of the stem, which has a larger cross-section than the distal stem.
  • the stem of the present invention is designed so that the lateral surface very nearly contacts the lateral cortex proximally and then curves away from this cortex, approaching the other side of the cortex distally.
  • the most stiff media is laterally adjacent to the stem in the proximal region of the stem.
  • the lateral contact of the distal stem portion with the cortex serves to prevent subsidence of the stem.
  • an angular femoral prosthesis having a three-point cortical contact, has improved support and reduced stresses applied thereto.
  • Such femoral prosthesis may be constructed of known biologically inert materials and in sizes requiring minimal removal of biological material.
  • FIG. 1 there is shown a femoral insert 10 within a femur 12.
  • the femoral insert 10 includes a convex spherical head 14 adapted for rotational reception by a cup-shaped acetabulum prosthesis (not shown).
  • the head 14 is axially secured to an elongated neck 16 at one end 18.
  • a stem 22 is secured at the opposing end 20 of the neck 16.
  • the interface between the stem 22 and the axis of the neck 16 form an angle C of from 0° to about 5°.
  • the stem 22 comprises a proximal portion 24 having a proximal medial endpoint 25 and a distal portion 26 having a distal media endpoint 27, the proximal portion being secured to the neck 16.
  • the distal portion 26 forms an angular continuation of the proximal portion 24.
  • the stem 22 is generally rectangular in cross-section, however, the medial side is rounded, as shown particularly in FIGS. 3 and 4.
  • the proximal portion 24 is generally constant in cross-section, approximately 1.0 inch by 0.4 inch. There is no collar or overhang of the stem at the neck end 20.
  • the distal portion 26 tapers gradually along the medial side 28 and remains generally linear along the lateral side 30. At the point defined by the line 4--4 in FIG. 2, the dimensions are about 0.75 inch to 0.4 inch. At the point defined by the line 5--5 in FIG. 2, the dimensions are about 0.4 inch by 0.3 inch. As shown in FIG. 6, the distal portion 26 tapers in both cross-sectional dimensions as it approaches the distal tip 32, which is generally rounded.
  • proximal portion 24 and the distal portion 26 are angularly joined to form a generally curved shape.
  • an apex 34 is formed at the junction of the portions 24 and 26.
  • the ratio between the apical height A and the medial length B is between about 0.35 and 0.42.
  • the exact ratio depends primarily upon the stem size required for the particular femur involved. Stem sizes are selected so that the desired relationship of three point contact between the stem and femur can be achieved for the most anatomical configurations. The only significant change necessary for proper fit is the length of the proximal portion of the stem.
  • the curved distal portion of the stem is oriented in the desired manner for any size medullary canal, leaving only the proximal portion to be varied for different proximal femur configurations.
  • the surgeon When an essentially linear stem is used, the surgeon must be concerned with the pivotal orientation of the stem in a horizontal plane. Even if the reaming is performed properly, a generally linear stem often will rotate when inserted into the cement-filled canal.
  • the reaming procedure for implanting stems in accordance with the present invention is designed to ensure proper orientation. After removal of the femoral neck, a calibrated reamer with a curvature identical to the actual insert is introduced close to the calcar and directed toward the lateral cortex. As it reaches the lateral cortex, the curved shape forces the reamer to slide towards the medial cortex 36. As in all reaming of femur, the surgeon must ensure that the reamer tip does not penetrate the cortex either laterally or medially.
  • Cement is then applied to the reamed canal.
  • the stem When the stem is inserted it is forced to follow the pre-reamed canal, no other position being possible.
  • the stem slides on the calcar, towards the lateral cortex and then angles medially, ultimately contacting the medial cortex.
  • the desired three triangular contact points are formed: in the calcar region, the lateral cortex and the medial cortex.
  • the lateral cortical contact point is at a point in the proximal portion. Bending stresses are applied to the proximal portion which has a greater cross-section than the distal portion.
